Message Carrier Entropy Optimization for Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Access control systems with non-networked message hosts face challenges in ensuring efficient dissemination of policy updates due to the lack of direct communication with centralized control systems, leading to difficulties in maintaining system security and performance.
Innovation Solution
A method is introduced to measure and optimize information dissemination performance in two-colony systems using message carriers, which involves analyzing message host and carrier information to determine communication efficiency and proposing configurations to improve message propagation, employing Markov Chain Monte Carlo simulations and weighted adjacency matrices to model and simulate information flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If non-networked message hosts are used to reduce installation and maintenance costs, then device complexity and cost are reduced, but information dissemination efficiency and reliability deteriorate
Solution Approach 1:
The patent introduces message carriers (mobile devices such as smartphones, tablets, or wearables) as intermediaries between the centralized control system and non-networked message hosts. These carriers receive policy updates from the centralized system via wireless communication and deliver them to message hosts in the local area, enabling reliable information dissemination without requiring direct network connections to all hosts.
Solution Approach 2:
The system enables message hosts to autonomously receive and process policy updates when a message carrier is present in their vicinity. The hosts independently store and execute policy information without requiring continuous network connectivity or centralized management intervention, reducing system complexity while maintaining operational reliability.
2Adaptability or versatility
If message carriers are used to propagate messages between non-networked hosts, then information dissemination is enabled without direct network connections, but information loss and incomplete policy propagation increase
Solution Approach 1:
The patent implements a feedback mechanism where message hosts send acknowledgments to message carriers confirming receipt of policy updates. The centralized control system receives these acknowledgments and can track which hosts have been successfully updated, enabling it to re-transmit updates to any hosts that missed them, thereby ensuring complete information dissemination.
Solution Approach 2:
The system pre-establishes communication protocols and message formats between centralized systems, message carriers, and message hosts. Policy updates are prepared in advance with complete information and structured data formats that ensure all necessary parameters are included, reducing the risk of information loss during transmission through multiple intermediaries.
3Ease of manufacture
If colonies of message hosts and carriers are used for decentralized communication, then system autonomy and ease of deployment improve, but measurement and analysis of communication efficiency become more difficult
Solution Approach 1:
The patent replaces complex manual measurement and analysis methods with automated computational algorithms. Software agents running on message carriers and hosts automatically collect communication data, track message propagation, and calculate performance metrics such as dissemination time, coverage, and efficiency, simplifying the measurement process while maintaining accuracy.
